By leveraging 3D printing and off-the-shelf parts that are easy to source; just a handful (chuckle!) of potentiometers, some servo motors and one from any number of ESP32 dev boards and you’re done.

On the other hand, the Serial Servo based on ESP32 is a dedicated driver board for Serial Bus Servos, capable of controlling up to 253 servos simultaneously via the ESP32 serial port.

I always love it when someone builds a teeny-tiny version of a common device or machine. There's just something so cute about it, almost as if it were invented by some mad scientist trying to avoid ...

“The SwarmDrive board contains a basic motor driver setup together with a powerful, Wi-Fi-and-Bluetooth-enabled microcontroller (ESP32) and USB connectivity.

Since [Hans] had a pile of Dynamixel servo motors lying around to test it with, a good first project for the platform was a simple self-balancing wheeled robot. (Video, embedded below) ...
